Abstract: To improve the breaking of a roving between a pressing finger bed and a fully wound bobbin preliminary to a bobbin change, the roving is initially wound around the tube above the upper cone and an unwound roving reserve is formed from at least a half turn on the upper winding cone and the body. A false twist is generated to provide a weakened region so that the roving has a first segment extending from the upper edge of the upper winding cone to the lower edge thereof, a second segment extending to the weakened zone and a third segment extending from the weakened zone to the pressing finger bed. The false twist increases the number of twists per unit length in the first segment and decreases the number of twists per unit length in the second and third segments. The pressing finger is moved along the bobbin periphery and the roving is broken at the weak spot by further movement of the pressing finger relative to the bobbin.
Abstract: In the case of ring spinning with condensing devices there is a risk that the yarns of the individual cops have a varying degree of hairiness. This can result in faults in the end product, for example a woven fabric. In order to avoid such faults, the ring spinning machine is connected to a monitoring station, in which the yarns are automatically monitored for hairiness; the cops, based on the monitoring results, are then automatically sorted.
